WINDOW.

Application led Mai-ch 16, 1925. Serial No. 16,031.

This invention relates to windows capable of use in various structures.

Briefly stated, an important object of this invention is to provide a window consistingl f or a number of sections having novel means numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of the improved window. the view illustrating the inside ot the window frame and the glass panes can ried thereby.

Figure 2 is a vertical transverse sectional view through the improved window frame and window section.

Figure 3 is a detailed horizontal sectional view taken on line 3--3 of Figure 2.

Figure 4 is a detailed horizontal sectional view through the upper portion of the improved window.

In the dra-wing, wherein for the purpose of illustration is shown a preferred einbodiment of the invention, the numeral 5 desig nates a window frame having stiles 6 and upper and lower rails 7 and 8, respectively.

rlhe frames 10 of the lower sash have their outer edge portions rabbeted as indica-ted at ll and intertit with the rabbeted portions l2 of the window frame, whereby to provide a three point contact between the sash and the window frame. By thus providing this three point Contact between the window frame and the sash a substantially dust and airtight connection is provided. Suitable hinges 14 may be employed to hingedly connect the lower sash to the window frame and locks 16 are carried by the inner side of the lower sash to hold the sash in closed' position. Figure l. plainly illustrates that the locks 16 are provided with bolts which engage eyes or suitable keepers 18 which that the inner rails of the sash are double rabbeted as indicated at 24 and are inter locked to provide a multiplicity of bearing spaces by means of which the passage of air is effectively prevented. ln addition to thier the inner rails of the sashes are provided with flanges 26 which overlap the inner stiles and therefore cooperate with the rabbeted portions in establishing a dust and air-tight connection between the parts.

Coming now to the description of the upper sash 3Q, it will be seen that the same is hingedly connected as indicated at 32 to the stiles 6 and are rabbeted as indicated at 36 for .contact with the rabetted portions of the same and the upper center member 38. Figure 4 illustrates that the rabbeted portions 36 by being arranged in the manner illustrated provide athree point bearing surface between each sash and the window frame.

Figure 4 also illustrates that one of the stiles of one of the upper sashes is provided with a ane'e or sealing strip 40 which overlaps the adjacent stile and therefore co-opcrates with the rabetted connection between the parts in establishing and maintaining a dust and air-tight connection between the parts. l

Figure 2 illustrates that the improved wiiidow consists of inner and outer sashes arranged in spaced relation and the upper outer sash may be held in place by fastening devices 44 while the lower sash may be held in place by fastening devices 46 of any suitable type.

In carrying out the invention the upper sash may be provided with rotatable locking lugs or fingers 43 which, may be moved into locking engagement with the center post 38 whereby to hold the upper sash against outward movement. f

Having thus fully described my invention what is claimed isz*- The combination with a frame having stiles, rails and horizontal and vertical intermediate members, inner and outer closures vertically hinged to said Stiles and consisting of upper and lower sash having rabetted edges, the edges of said stiles, said rails and said horizont-al and vertical intermediate the Vertical intermediate members whereby to Cooperate with the Connection between the vertical intermediate members and the npper sash in providing aeubstantially air and dust-proof connection between the parte aforesaid. sealing strips overlapping the meet-ing p01 tions of the upper sash at points spaced from In testimony whereof I aix my signature.
